Simulation of Tropospheric Ozone Concentrations at the Regional Scale During the Summer of 1988

PIS将测试和应用嵌套的光化学和气象模式，以确定它们模拟地球边界层中臭氧、氮氧化物以及人为和生物碳氢化合物的产生和输送的能力。具体地说，PIS计划模拟一个月期间对流层臭氧的光化学产生和输送以及北美东半部和西大西洋区域(1988年夏季)，比较模拟和观测到的农村和城市臭氧浓度，并找出两者之间差异的原因，比较与臭氧产生有关的其他物种的模拟浓度与观测值，评估预测浓度对不确定模式输入的敏感性，调查对温度的敏感性，并为选定的农村和城市应用优化嵌套区域尺度模式的设计。

The PIs will test and apply nested photochemical and meteorological models to ascertain their ability to simulate the production and transport of ozone, nitrogen oxides, and anthropogenic and biogenic hydrocarbons in the earth's boundary layer. Specifically, the PIs plan to simulate photochemical production and transport of tropospheric ozone over a period of one month and an area which encompasses the eastern half of North America and the western Atlantic Ocean (summer 1988), to compare simulated and observed rural and urban ozone concentrations and to identify the causes of discrepancies between them, to compare simulated concentrations of other species related to ozone production with observations, to evaluate the sensitivity of the predicted concentrations to uncertain model inputs, and investigate sensitivities to temperature, and to optimize the design of a nested regional- scale model for selected rural and urban applications.
